Cast Steel Floating Ball Valve

The ball of the floating ball valve is floating, and under the action of medium pressure, the ball can produce a certain displacement and press on the sealing surface of the outlet section. Simple structure, compact design, good sealing performance, sealing surface and ball valve are often in a closed state, not easy to be eroded by the medium, suitable for general industrial media such as water, solvents, acid and natural gas, and also suitable for media with relatively poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene and other media. Floating ball valves mainly include cast steel two-piece floating ball valves, forged steel two-piece floating ball valves, forged steel three-piece ball valves and one-piece cast floating ball valves.
